HIGH-INTENSITY RED LIGHT DISPLAY DEVICE A display device which is especially suited for application as a center-high-mounted stop-light (CHMSL) or brake light for an automotive vehicle includes a white linear light source. A coupler panel or sheet formed of a fluorescent dye-doped material couples light from one edge therethrough to an opposite edge from the light source to a light receiving edge of a display panel. The coupler panel transmits red light therethrough, absorbs other colors of light, and re-emits the absorbed light as red light. The display panel has a first surface formed with optical quality, light reflecting grooves, which reflect and disperse the edge coupled light out a second surface which is opposite to the first surface. The display panel viewed from the first surface is transparent at all times. The display panel viewed from the second surface produces a red light pattern reflected from the grooves when the light source is turned on, and appears transparent when the light source is turned off.
